VALVE-GRINDER.

Specification of Letters Patent` Patented` Dec. 27, 1921.

Application led November 29, 1920. Serial No. 427,173.

To all whom t may concern Be it known that I, ANTON EMANUEL CARLSON,Swedish subject, (having declared his intention of becoming a citizenofthe United States,) residing at Merchantville, in the county ofCamden, State of New Jersey, have invented a new and usefulValve-Grinder, of which the following is a specification.

My invention consists of a novel construction of a valve grinder,wherein I employ a casing inclosing the principal operative parts, saidcasing having one side thereof removable and being provided at its upperand lower ortions with bearings for the spindle employed, said spindlehaving at its upper portion a pinion in mesh with a rack carried by ayoke, said yoke being operated by suitable cam mechanism, whereby thecontinuous rotation of the outer handle will impart an oscillatorymovement to the spindie and its adjuncts.

It further consists of a novel construction of mechanism fortransforming the rotary motion of the actuating handle and cam intooscillatory motion, the lower end `of the oscillatory spindle beingprovided with a suitable valve engaging implement, whereby the valve isoscillated upon its seat, according to requirements.

t further consists of other novel features of construction andadvantage, all as will be hereinafter fully set forth and pointed out inthe claims.

For the purpose of illustrating my invention, I have shown in theaccompanying drawing, oneb form thereof which is at present preferred byme, since the same will give in practice satisfactory and reliableresults, although it is t0 be understood that the variousinstrumentalities of which my invention consists may be variouslyarranged and organized and that my invention is not limited to theprecise arrangement and organization of these instrumentalities asherein shown and described.

Figure 1 represents a side elevation of my novel construction of valvegrinder, the cover of the casing being removed.

Fig. 2 represents a section on line 2-2 Fig. l, certain of the partsbeing shown in elevation.

Similar numerals o reference indicate corresponding parts.

Referring to the drawings 1 designates my novel construction of valverinder, the same comprising a casing or bo y member 2, in which theoperative parts of my invention are contained, said casin at its upperportion carrying the hand e member 3, having the hand piece 4. The upperinner wall of the casing contains the seat 5, into which is stepped theend (j of the spindle 7, on the upper portion of which is pinned thesleeve 8 of the pinion 9, so that the latter and said spindle rotate oroscillate in unison, said spindle and. pinion being retained in theirproper position by the lower collar 10 pinned to said spindle, saidcollar bearing on the lower wall 11 of the casing 2.

The pinion 9 is in mesh with the rack or segment 12, which is carried onthe top of the yoke 13, the latter being composed of the top 14, whichcarries the rack 12, the parallel sides 15 and the bottom 16 whichoscillates on the pin 17, the latter having a head 18, and its outer endbeing secured or pinned in the boss 19.

The inner parallel walls 20 of the yoke 13 contact with the periphery ofthe cam member 21, the latter being of the form of a disk eccentricallysecured to the pin 22, which is mounted in the boss 23 and seated orpinned in the seat 24 of the handle 25.

The operation is as follows As the handle 25 is rotated, the pin 22 andthe cam or eccentric member 21 will be continuously rotated and thecontact of the periphery of said cam 21 with the walls 20 will impart anoscillatory movement to the yoke 13, whereby the rack 12 will oscillatefrom right to left, thereby imparting an oscillatory movement to thepinion 9, the spindle 7 and its adjuncts.

By the provision of the handle 4, the opcrater can readily exert alongitudinal thrust upon the spindle 7 so as to exert the desiredpressure upon the valve during the act of grinding the same upon itsseat.

By the provision of the seat 5 a stepped bearing is formed in the upperportion of the casing 2, so that the spindle is effectively guided atits upper end 6 and at its intermediate portion where it has its bearingin the lower portion of the casing 2.

The collar 10 retains the spindle and pinion 9 and their adjuncts in theproper position with relation to the rack 12 and the yoke 13 is at alltimes properly positioned during its oscillatory movement by reason ofthe head or fiange 18 on the pin 17.

Upon the removal o1 the plate or closure 26, all the parts are readilyaccessible, as will be understood from F ig. 1, for the purpose ofinspection, replacement or repairs, and upon the removal of thetransverse pin which secures the pin Q2 to the handle and the removal ofthe transverse pin which secures the pin 17 in its boss, all the partsare readily accessible in case it is desired to replace any of the same.

The blade or implement 27 at the bottom et the spindle 7 is providedwith the projections 28, Which are adapted to engage the valve, and itivill be apparent that the plate or implement 27 can be used in theposition seen in Figs. l and 2, or, it desired, it can be reversed andthe projection 28 caused to engage the valve or other member to begroundor oscillated. The implement 27 is held in its desired position by meansof the iiat spring 29 having a pin 30 thereon, which is adapted toengage the holes 3i or 32, according` to requirements.

lt will be apparent from the oregoinfr that I have devised a novelconstruction or valve grinder, Which Will be cheaply manufactured andWill be durable and effective under all conditions, and which is notliable to readily get out of order.

lt will now be apparent that I have devised a novel and usefulconstruction of a .valve grinder, which embodies the features l claim asnew and desire to secure by Letters latent, is

l. ln a valve grinder, a casing, a removable plate at one side thereo't,a spindle having its upper end stepped into the upper portion of saideasing and its intermediate portion rotatably mounted in the lowerportion of said easing, a pinion on the upper end of said spindle, ayolre pivotally supported at its lower end in the lower portion or saidasing, a. cam member eceentrically mounted on a rotary pin journaled insaid casing, a rack on the upper end ot said yoke engaging said pinion,and a handle connected to said pin for continuously rotating the latter,thereby imparting oscillatory motion to said spindle.

2. ln a valve grinder, a casing, a spindle having its upper end providedwith a bearing in the upper portion of said casing and its intermediateportion rotatably mounted in the lovver port-ion ott said casing, apinion on the upper end of said spindle, a yoke pivotally supported atits lower end in the lower portion of said casing, and provided withinternal parallel Walls, a cam member Within said easing and having itsperiphery engaging said parallel walls, a rotary pin on Which said cammember is eceentrically mounted, said pin being journaled in saidcasing, a rack on the upper portion ot said yoke engaging said pinion, acollar on said spindle adapted to engage the lower portion ot' saidcasing, and thereby to retain said pinion in mesh with said rack, and ahandle connected to said pin for continuously rotating the latter andsaid cam member, thereby imparting oscillatory motion to said spindle.
